A certain game involves tossing 3 fair coins, and it pays 12 cents for 3 heads, 7 cents for 2 heads, and 4 cents for 1 head. Is 7 cents a fair price to pay to play this game? That is, does the 7 cents cost to play make the game fair?

step-by-step explanation:

ok so im not 100% sure but you would start by adding 5.1t and 1.9t beacuse they have the same variable. that is 7t.   then add -3.6 + 1.2 which is -2.4

so then keep that as -2.4 + 7t. i apologize if this is incorrect. best luck on your test < 3
